When I decided to participate in the blogger's action day on Climate Change, I knew I was not going to post a litany of scary statistics. I've read all those things and it hasn't made me hopeful or optimistic. Instead, I wanted to ferret out and post some good news, news about how the world may be adapting and how people are coming up with good ideas.

Good news is hard to find. I've looked for about seven hours, total, and come up with only three articles which I think are hopeful enough to include. There are others that have a hopeful sounding headline but which when you read them, are actually gloomy as hell. For example, the headline "Global Warming expands Trees Range" would seem to be good news. But in fact, the article went on to detail the results of studies on whether or not trees can grow at higher latitudes/altitudes due to temperature changes. The widespread assumption was that yes, they uniformly would. Turns out, not so much. Only half of the sites examined showed any evidence of saplings growing in previously inhospitable areas. In a few areas, treelines had retreated.
This brings me to another thing. One of the things I hear a lot from skeptics is that global warming - if it's even happening - is good because plants can use more CO2 as fertilizer and will increase their growth rate. Well, that's true up to a point - and the point isn't very far away. First year Ecology, people. Ecology 101. Growth is limited by that necessary factor in the environment which is present in the LEAST amount. In other words, jack up the carbon dioxide all you like, but your hours of daily sunlight ain't gonna change. Or your soil quality. Or your WATER. There are a lot of marginally productive areas which are rapidly losing their margin due to desertification.
Okay. I did find one tiny scrap of halfway decent news today. If you can call it that.
